Patented Apr. 25, 1933 UNITI-:D STATES PATENT- oFFlca i' GEORGE A.BINDER, OF CHICAGO, rumors, AssIGNoR 'ro ROBERT MALCOM, or CHICAGO,

`ILLINOIS f GOGGLES My inventionrelates more particularly to V'gogglesinvolving eye-cups adapted to more or less closely fit about the eyes ofthe wearer; the invention having for its object the provision of meansassociated with the lenses .whereby lproper circulation of air about thelens and within the lens holding end Vof the eye-cup may be obtained andthe formation of condensate on the lens interior or fogging of the lensprevented. s

My invention also involvesmeans whereby the degree of air circulationmay be regulated in lkeeping with the desires and needs of the wearerunder Varying conditions of use.

The objects and advantages of my invention will be readily comprehendedfrom the following detailed description of the accompanying drawingwherein:

Figure 1 is a transverse sectional elevationV and machinists whenworking with welding torches, abrading machines, metal chipping and thelike, requiring full eye protection and therefore goggles which willconform more or less to the face and fit comparatively closely about theeyes. `Considerable Adiiiiculty and discomfort has been encountered withgoggles of this character, due to lack of proper ventilation within theeye-.cups and particularly adjacent to the inner face or side of thelens, causing the lens to become fogged and vision made indistinct.

For purposes of eXem'plification, I have .disclosed my invention applied'to agoggle eye-cup of the type especially adapted to be used by amechanic whose eye-sight necessitates the constant wearing ofeye-glassesor spectacles. Y

Therefore, the temple side of the eyefc'n" wall 1() is shown moulded orprovided witii an outward off-set or spectacle arm receiving socket at11 disposed transversely of the eyen cup W-all from outer or lens endtoward the inner orrface engaging perimeter, where it terminates in aslotted ear 12 intended to receive the usual headstraps whereby thegeg.- gle is secured in place. As the eye-cup construction thus fardescribed is no part of my invention, further detailed description ofthe general wall formation of the eye-cup need not be entered into. i i

The eye-cups are usually made of a mould,- able material, such asbakelite, so Aas, to providethe wall with sufficient strength andrigidity while at the same time being `comparatively light in weight. 1

The wall at the outer or lens receiving kend on the eye-cup interior andsomewhat removed from the outer perimeter is shown provided with anannular shoulder 13; while the interior of the cupbeyond the shoulder isshown threaded V,to receive the externally threaded flanged ring 14,whose iiange yis intended to lap the outer perimeter of the eyecup asshown; the ring'l4 being intended to hold the lens 15in place. Y

v The annular shoulder 13 is shown provided vvith a plurality ofcircumferentially spaced notches. .or grooves, as at 16, vdisposedtransversely ofi the shoulder.; while the threaded main body portion ofthe ring 14 is likewise provided with plurality of cut-.out portions orslotsdisposed transversely .of the inner threaded portion `as t ShOWLlat 17 in Figures 2 and 5.

The lens 15, as clearly shown in Figures 1 and 2, is of a diametermaterially less .than the diameter of the threaded portion ,of theeye-cup; and the lens 15V is provided .with a beveled perimeter 18tapering inwardly toward the outer face of the lens, This beveled edgeofthe lens will cause the jlens'to be centered when the ring 14 isscrewed-into contact therewith and as a result an annular space at 19will be provided .beneath the Jring 14 and .Surrounding the edge ofthe.ansia '10 lao vided with the transverse notches or slots23.'k

extending through'the walls on opposite sides of the circumferentialgroove 22, see Figure |3; with the notches or slots 23 on the inner wallor perimeter of the ring extending down and through to the oppositesidep'or annular face of the ring 21, as shown at 24 see Figures 3 and4; while the notches or slots 23 on the 'outer perimeter of the ring areof depth substantially equal to the depth of the annular groove 22'.

When the ring 21, which is of larger diameter than the lens, is arrangedin the eye-cup vwith the annular groove 22 in the ring disposed towardthe lens 15, the inner or lower ends 24 of the slots 23 will communicatewith the goggle interior beneath the lens, while slots 23 will registeror communicate with the annular space 19 with which the slots 17 in thelens holding ring 14 also communicate. It is apparent, therefore, that aplurality of continuous air passages, leading 'from the exterior to theinterior of the eye-cup, or vice versa, will be provided as shown at inFigure 1.

Furthermore, these continuous passages 25 also communicate with theannular groove 22 in the face of the ring 21, thus allowing some of theair'to flow around'in the groove and to discharge through the lower orinner ends 24 of the slots 23. It is apparent that circulation of airthrough the eye-cup and across the inner side of the lens is permitted;and in order to permit such circulation, particularly in eye-cups asshown which are adapted to lit closely about the eyes, I show th-e sidewall o f the eye-cup preferably provided with two screened openings at26, 26.l

In my improved eye-cup, the lens 15 is not only' preferably beveled asshown and stated, but the lens diameter is also preferably suflicientlyless than the inner diameter of the threaded Wall portion of the eye-cupso that the peripheral edge of the lens intermediate of the oppositebevels 18 and 20 will merely engage atthe inner peripheral edge of theVentilating ring 21, as shown in Figures 1 and 2.

The lens, therefore, will not overlie or extend flush with the entireannular faces of the Ventilating ring and hence. will not entirely coverthe ends'of the slots 23.

At the same time, with the slots 17 in the lens clamping ring made ofsufficient depth as shown, the outer ends of these slots will remainuncovered and therefore permit air to enter the air space 19 beneath thethreadled end of the lens clamping ring,see Figures 1 and 2, this airspace in turn communicating with thev annular groove 22, which, in turn,communicates with the slots 23.

With the ring 21 arranged with its annular groove 22 disposed outwardly,namely toward the lens as shown in Figure 1, the maximum degree ofventilation is obtained.

. If for any reason a lesser amount of ven,- tilation or air circulationis desired, the

"wearer need merely remove lens clamping ring 14 and the lens 15 andthen reverse the Ventilating` ring 21 by disposing the grooved sideshown in Figure 3 inwardly or away from the lens, with the ungroovedside shown in Figure 4 disposed toward the lens as shown in Figure 2,and thus obtain a minimum degree of circulation, as a lesser amount ofthe air, which passes through the slots 17 in the lens clamping ring 14into the air chamber or space 19, can pass through the uncovered portion24 at the base of the slots 23 to the in-V terior of the eye-cup, orviceversa; this being possible because the extreme peripheral edge ofthe lens merely rests on the inner perimetrical rim of the Ventilatingring 21. p

It is apparent that the inner ends 24 of slots 23 in the ring willcommunicate with the goggle interior. Furthermore, as the slots 23communicate with the annular groove 22 in ring 21, a minute amount ofair will enter groove 22 and allowed to circulate through the slots 16formed in the ring-seat or shoulder 13 of the goggle. As is evident, alesser amount of air circulation is obtainable with the ring 21 arrangedas shown in Figure 2 than is the case where the entire groove 22 is opento the annular air space 19 at the perimeter of the lens. f

It is apparent that although air circularoi tion about the lens ispermitted, the passages a i are not only rather minute but of anindirect nature thus preventing passage of undesirable foreignparticles.
